In recent years, the study of volumetric ignition using high-speed (nanosecond) pulsed low temperature plasma for gasoline engines was reported by authors [ 1 ]. However, the fundamental analysis of ignition characteristics of the low temperature plasma ignition and the analysis of combustion initiation mechanism of the low temperature plasma ignition was not enough in the previous paper. In this study, a low temperature plasma igniter of a barrier discharge (silent discharge) model was developed for trial purpose. A fundamental analysis of ignition characteristics was carried out when the low temperature plasma ignition was applied as the ignition system for gasoline engine using single-cylinder. The difference between the ignition characteristics of the low temperature plasma and the thermal plasma of a conventional spark plug was investigated by comparing a combustion characteristic of both in various driving conditions.
